Title: Device for securing uniformity of movement in the reproduction of sound films
IPC: G03B31/02
Filed: 1929-09-20
Abstract: 338,652. Selenophon Licht-und Tonbadges. March 27, 1929, [Convention date]. Sound-reproducing apparatus associated with kinematographs; film - feeding mechanism. - Consists in the provision, in talking motionpicture apparatus, of special means for obtaining uniform movement of the film past the sound-reproducing device, and also for facilitating proper threading of the film through the machine, so that when the apparatus is running there is the appropriate length of film between the picture gate and the sound gate. The combined soundrecord and picture film is drawn through the picture gate 1 and the sound gate 5 by an intermittently rotated wheel 2 and a sprocket wheel 8, whilst a drum 6 associated with a flywheel, over which drum the film passes after leaving the gate 5, is provided to ensure uniform movement of the film through the sound-reproducing device.. Between the drum 6 and the sprocket 8, the film passes over a jockey roller 7 mounted on a pivoted arm 9 which is normally drawn against a stop 10 by a spring 12. Rollers 3, 4 arc also arranged between the wheel 2 and the gate 5 as shown. When the film is threaded through the machine it is first drawn taut against the rollers 3, 4, 7, the roller 7 being in the position shown in full lines: Then on starting the driving mechanism, the drum 6 is set in rotation gradually, on account of the inertia of the flywheel, and the loop between the members 6, 8 is shortened, the'jockey roller being lifted until the arm 9 is held by a spring catch 14. At the same time, a corresponding elongation of the loop between the parts 2, 4 occurs, the film rising from the roller 3 as shown in dotted lines. The length of film between the picture gate 1 and the sound gate 5 is then such that the part of the sound record positioned in the gate 5 for reproduction corresponds with the picture in the gate 1 which is to be projected, and this correct distance is maintained throughout the run of the film. The roller 4 may be provided with a damping device such as vane-wheels.

Title: Improvements in or relating to machines for use in the manufacture of tyre casings
IPC: B29D30/44
Filed: 1920-10-13
Abstract: 173,895. Marks, E. C. R., (Fisk Rubber Co.). Oct. 13, 1920. Tyres, elastic, special apparatus for making.- An extensible band, which may be the tread or other part of a tyre cover, is fitted over a core by a series of fingers arranged to lift the band from an expanding clutch and then place the band (in polygonal form) over the core. The band a is placed over the arms c which are guided in radial slots 14 in one end cover of a fixed casing 11. Each arm c carries a pin 16 engaging a camslot 17 in a plate 18, which is oscillated to expand and contract the arms c by a quadrant 22 engaging a rack 21 on the plate. The quadrant 22 is pivoted on the casing 11 at 23 and carries an arm 24 having a roll 25 engaging a cam-groove 26 in one end of a cam-drum 27. The latter is keyed to a driven shaft 19. The fingers d, by which the band is transferred from the expanded arms c to the core e, are mounted in pairs on concentric shafts 30, 31 carrying rolls 33, 35 which engage cam-grooves 39, 40 respectively in the drum 27. When the band reaches the expanded position (indicated in dotted lines in Fig. 1) the pairs of fingers d are caused to enter the grooves g in the arms c. As the drum 27 continues its rotation, the arms c recede and the fingern d, now carrying the band a, move into a, position over the core e. In this movement, the shafts 30, 31 carrying the fingers d, are rocked to allow the fingers to clear the core. The pairs of fingers are next caused to separate so that the band a is freed to contract on to the core. The movement of the fingers d is then reversed to position them for the next pick-up from the arms c. The roching-movements of the fingers d are effected by toothed gearing arranged at the opposite end of the casing. In the preferred construction shown, the cycle of operations is effected during a half-revolution of the cam-drum. For this nurpose. the shaft 19 is adapted to be driven at half-speed from a countershaft 67 which is given one complete revolution through a treadle-controlled clutch. The clutch-mechanism shown in Figs. 6 and 8 comprises a collar 69 fast on the shaft 67 and carrying a dog 73 which is spring-pressed into the path nf lugs 71 on the boss of a continuously-rotating loose pulley 70. The dog is normally held retracted bv a bar 84 engaging a notch R2 in the dog. The bar is withdrawn against the action of a spring 90, Fig. 1, by the depression of a treadle 89. A groove 91 in the collar 69 leads to an inclined face 81 of the notch 82 so that, on release of the treadle, the bar 84 operates to withdraw the dog 73 at the end of a revolution.

Title: Improvements in or relating to machines for assembling box parts
IPC: B31B17/00
Filed: 1927-11-01
Abstract: 305,252. Jagenberg, E. Nov. 1, 1927. Machines for assembling box parts. In a machine for applying.the lids or covers to body parts automatically and in rapid sequence, the body parts, after being brought to the point at which assemblage takes place, remain stationary in a horizontal position and the lids are then fitted from above by means of guide members; by this arrangement lids can be fitted on to filled boxes. In the arrangement shown in Figs. 1 and 4, the body parts 3 and lids 4 are fed by parallel staggered belts 1, 2 respectively' into guide channels arranged transversely to the belts; a pusher device 8, 9 then moves the parts against stops to the assembly position where the lid 4 is supported on spring-controlled pivoted rails 13 and the body part 3 over apertures 23 in a table 24. A rod 14, carrying pivoted levers 17 spring- pressed against a plate 18 on a rod 19, is then moved upwards and spring fingers 22 on the levers 17 pass through apertures 23 and enter the cover 4 which, with the fingers, is moved downwards by a plunger 25, past the rails 13 on to the body part 3; the fingers and plunger then return to their original positions. The plate 18 may be actuated during the upward movement of the fingers to move the latter inwards to press the sides of the part 3 slightly inwards and during the downward movement of the fingers, they are pressed outwards to bend the edges of the lid slightly outwards. The assembled box is pushed past a cam-operated stop 10 on to a shoot &c. 27 by a succeeding body part and may then be led to a labelling machine. The parts of the machine may be adjustable to allow for varying sizes of boxes and the spring fingers may be arranged to fit the lids of oval or round boxes. The edges of the box parts may be pressed in before they are fed to the assembling position by plungers provided with spherical heads. The assembled boxes may be moved through channels fitted with spring-pressed rollers which press the sides of the boxes inwards and rectify any alterations in the shape thereof. In another assembling device the lids are fed sidewavs into a threesided pivoted frame, which, with a lid is swung downwards through 90‹ to fit the lid on to a bodv part fed beneath it or the frame may be arranged to swing through 180‹ when the lids are fed into it with the tops underneath. In a further form the lids are fed into a tapering guide shaft disposed over the assembling point, a plunger then pushing the lid on to a body part.

Title: Improvements in or relating to separable fastener elements
IPC: A44B18/00
Filed: 1968-06-19
Abstract: 1,206,321. Shaping separable fasteners. VELCRO S.A. 19 June, 1968 [22 June, 1967], No. 29316/68. Heading B5A. [Also in Divisions D1 and E2] An element for a separable fastener, Fig. 9, comprises a flat flexible backing sheet BS supporting flexible pile-like protuberances in the form of resilient perpendicular hooks and loops attached to the base sheet BS by means of parallel spaced strips of adhesive material. The element is formed from prefabricated male ML and female FN webs, Figs. 10-13 (not shown), and 4, e.g. of thermoplastic material, the male web ML comprising parallel monofilaments 24 carried on strips 20, each having a bead 14 of resinous adhesive material, while the female web FM comprises a grid of monofilaments 26 mounted on parallel adhesive strips 28. The male web monofilaments 24 are formed into resilient hooks 16, Fig. 9, which engage releasably with raised resilient portions 32 of the female monofilament grid of a second fastener element. In production the male ML and female FM webs are fed into a machine, Fig. 2, being progressively narrowed and contoured by the action of endless tool bands ABCD as they pass continuously through the series of relative path configurations, e.g. Figs. 4, 6, in a zone 50 held at just below the fusion temperature of the monofllaments. The adhesive strips 28 of the female web FM are brought into alignment with the adhesive beads 14 of the male web ML, Fig. 4, the forming band D being depressed by a series of progressively lower rolls 90. The bands A and B converge by the action of guide rolls (92), Fig. 1 (not shown), and the female web FM is embedded into the adhesive beads 14, bonding the webs together, Fig. 6. The webs then pass into a zone 52 where rapid cooling, e.g. by refrigerated air, renders the monofilaments relatively brittle; the central portion of each male strand 24 may then be cut out by circular saws 122, leaving a pair of hooks 16, Fig. 6, or by vibratory cutting tools (not shown).  Detector fingers (158), Fig. 7 (not shown), projecting upwardly into the recesses 78 of the bands C, are connected by any strands remaining uncut, hence operating an electric switch to stop the machine. The backing sheet BS, supplied from a spool 148, is welded on to the beads 14 of the combined webs at a final assembly station, 132, and Fig. 7 (not shown), by an ultrasonic device 144, the finished strip of fastener element finally being cooled, e.g. by a refrigerated air stream, at a cooling station 164 before winding on to a reel 176 prior to cutting up for use. Shape retention of the filaments may be enhanced by adding filling material, e.g. floe, to the adhesive material employed.
